I had exactly the same problem, I tried to clean the carb several times without any luck. I gave up on the carb as it was an EPA style without adjustable mixture needles. Bought a new carb for it, installed it and the engine fired up right away. Took me 10min to let it warm up and dial the mixture, it has been fine ever since.

I recommend to buy the replecement carb old-new stock mfg pn: 632334A Tecumseh Carburetor with mixture needles

This place helped me out with one.

The Tecumseh snow motors are notorious for idling rough. Especially the last few years of production. Most service techs just say "live with it" But there are a couple of things you can do to help.
It is not a carb adjustment issue. It's usually a fuel, clean carb issue.
First, use a premium grade fuel without ethanol and a fuel stabilizer. This will give you the best fuel mix.
Second, Remove the carburetor shield and clean the inside and outside of the carb with carb cleaner. Even though you can't see the carb usually, they do get varnish build up and cleaning it will help some.
Third, Put the recommended amount of fuel system cleaner in the gas. I use Sea Foam brand. Over a tank full or two you will notice a difference in how the engine idles.
Fourth, Use a high quality spark plug and use a new one every year. Make sure the gap is correct.
Good Luck! Feel free to as any other questions you may have. Don't forget to rate this answer!

Why does my 1998 gmc jimmy rpm drop so low when its warm causing a miss in the engine


The truck ECM computer controls the idle speed based on a number of engine parameters. Idle drops to a minimum preset level when engine coolant reaches normal operating range and the engine goes into closed loop control. This idle is typically set at around 575 rpm, and cannot be changed without reprogramming the ECM. The miss is not caused by the idle speed - unless the engine is tuned properly and has not lost compression, this idle speed can result in a rough running engine at idle (typical with older 4.3L Vortec engines). Best bet is to get a complete tuneup which will include checking the O2 sensors, catalytic converter and cleaning the IAC valve and throttle body.

5.7 6 speed. Just started running rough miss firing at idle and lower speeds. Throws no codes.


Check for plug leads touching each other. Check for moisture in distributor cap if you have one. Check plugs and replace if necesary

1996 honda accord rough idle and dies


Do the following

Here are the most common causes of idle surge, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

Car engine interment rough idle


Sounds like possible vacuum leak. Next time it starts try spraying starting fluid around vacuum hoses, if engine speeds up, there is a vacuum leak at that point where you sprayed. Hope this helps.

When idleing once in a while it starts running rough and shaking truck, 1998 k1500 350. no engine light. when i gige it gas it smooths right out. engine seems like its a little louder than normal.


Here is the common cause of surges, cold stalls, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours.

To correct this problem Buy a can of throttle valve cleaner (it is made by CRC) from the local auto parts store, NEVER USE CARB CLEANING SPRAY, IT DESTROYS THE ANTI-STICK TEFLON COATING, spray it into the air intake through the throttle body of the engine until you have used about half the can, you will need to hold the idle up while you do this, it will try to stall, after this shut the engine down and disconnect the Negative (-) battery cable for 5 minutes. The intake is now clean, if you continue to have the idle speed control problems you may need to seek the help of a professional.

My checkengine keeps coming on the code is p507


If the engine is running rough at idle (although idle speed is normal), then you might have a vacuum leak. This results in a lean air/fuel mix condition and the ECU might over-compensate by trying to "richen" the air/fuel ratio.

Vacuum leaks are unpredictable and not always easy to locate; sometimes you pop the hood open and it's right there staring at you --- a cracked or disconnected vacuum line! Reconnect and it's good to go. The check engine light will turn off after you complete a drive cycle.

If the idle speed is too low or jumping up and down, your IAC (Idle Air Control) motor may be malfunctioning and in need of replacement.


Hope this helps.


Have a Great day !!!

Poulan chainsaw 46cc 20" chain


You normally have 3 screws - idle speed - slow running and fast running.
First take care as if it runs faster than idle speed that chain will be whipping around also.

Second you have to determine what is the problem. Is it faulty at low speeds or high speeds ? or won't it idle.
If it has turn stops fitted to the screws you only have a small adjustments either way.

If it won't idle, try turning in the idle screw a half turn - until the chain just starts to move slowly.
If its dying at slow speeds, get is going and slow turn the slow screw out until it starts to run a bit rough then turn it back in to the point where its running smoothly.

Bad fast speed can be caused by simple things such as a blocked muffler ( insects too - I had one blocked off by a mudnest wasp) - otherwise get it running at full and adjust the fast screw as per the slow one - out till its rough then back in slowly until its smooth.

Suggest before all this tho that you get it running with the cover off the carby and then give it a good squirt of carby cleaner first - it may just clear out any 'poop' thats there.

(Have faith even tho I have a Poulan with a carb that refuses to run on anything but carby cleaner. I have pulled it apart a few times and renewed all the perishable bits buts its a real pig)
